Sifting sand at Caesarea, volunteers Hillary Ganz and Matthew Kesselhaut of the University of Maryland search for tiny ancient remains, such as coins, bones, teeth, bits of pottery and beads, easily overlooked in buckets of excavated earth. Behind them the restored Crusader citadel, with a modern restaurant on top, rises above the breakwater of King Herod’s harbor.
